ric, to break into clearing up that infection please start with these tools:
==Get CCleaner from http://www.ccleaner.com/ - and install it in a new folder. You should keep this one for general use. I set the installation checkboxes only to open from the recycle bin. It's neater that way.
Now run CCleaner from the recycle bin rclick menu using its default settings [if you set up CCleaner as i suggested, rclicking the bin icon should give you the Open CCleaner option...].
If you have FireFox open the Applications tab and ensure at least that Cookies and Cache are checked.
Select the Cleaner icon, press Run Cleaner.
[For future quick temp file cleaning select the options you wish to use via the Windows and Applications tabs ..]
==GET AVG antispyware 7.5 here.. http://free.grisoft.com/doc/5390/lng/us/tpl/v5#avg-anti-spyware-free
-Install it and UPDATE it.
Start AVG a-s 7.5;
-under Scanner/ Settings please change the default action from Recommended Actions to QUARANTINE, and run the complete system scan.
-press Apply all Actions and Save the log file. Post the log file.
==Download this file to your desktop: http://download.bleepingcomputer.com/sUBs/ComboFix.exe
- to run it dclick combofix.exe and follow the prompts to start it. When finished, it will produce a log, C:\Combofix.txt - post that log in your next reply.
A word of caution - do not touch your mouse/keyboard until the scan has completed. The scan will temporarily disable your desktop, and if interrupted may leave your desktop disabled. If this occurs reboot to restore the desktop.
Post those two logs along with a fresh hijackthis log.

Come on dude, don't click on this thing ever...ever. just try to get a few scanning softwares and scan you pc to get rid of any infections. CLickin on em is basically givin them permission to install whatever the heck they want.

Make sure you use a firewall to keep yourself safe from these things, Free version of zonealarm is good and comodo is a good one as well. Use them.

try the virus and nasty section. Use the scanners recommended there and you should be able to sort it out.

Also check yourself, see if you find anything unusual installed on your pc at roundabout the time when you started experiencing the problem, If something has been installed and you do not recognise it, then that could be part of the problem. Check it and delete it if its not something you authorised. Make sure you check out the virus and spyware section as you can get real help from there. Good luck.

Oh yeah, almost forgot... wrong hijackthis. Delete your copy from your desktop and follow these instructions, please.
==download hijackthis: http://www.majorgeeks.com/download5554.html
-copy it to a new FOLDER placed either alongside your program files or on your desktop and then... rename hijackthis.exe to imabunny.exe
-in that folder start HijackThis by dclicking the .exe; now close ALL other applications and any open windows including the explorer window containing HijackThis.
-click the Scan and Save a Logfile button. Post the log here.
